I can see the same issue in my desktop with kdm, but I've never had
the energy to bisect or look further into it, so I just type halt or
reboot in xterm :-(

But the fact is that a few days ago I tried rebooting through kdm button,
but it left me with a console login screen (and no reboot).

It also happened a few times before too (and I am always using a
uptodated 2.6.25-rcX kernel).
